Methane gas hydrate is a crystal formed by the enclosure of methane molecules into a hydrogen-bonded network of water molecules under appropriate temperature and pressure conditions. Sufficient methane of biogenic and/or thermogenic origin exists in the earth’s crust and over the years has combined with water and formed hydrate. This naturally occurring gas hydrate is regarded as a future energy resource. At the present time, hydrate energy recovery technology is not available. Engineering limitations and economic barriers have prevented the exploitation of this resource. At the same time, naturally occurring methane hydrate is potentially threatening to the global environment if it decomposes as a result of the current climate warming. Calculations suggest that this is possible to occur in the distant future as it happened 55 million years and 13 500 years ago. This chapter discusses the connections between energy, environment, and methane gas hydrate. The significance to our society is also discussed.
